Definitions

• the present invention relates to an edge insulation structure comprising at least an elongated edge insulation and an at least elongated edge rail, wherein said edge insulation comprises an abutment face for abutting a foundation and a second abutment face for partially abutting an underlying insulation and an adjacent cast floor plate, for instance a concrete floor plate of a suitable thickness, wherein the edge insulation further comprises a face facing downwards and a face facing upwards, the edge insulation extending from a level below said floor plate and substantially up to the surface of the floor plate.
• the present invention further relates to use of an edge insulation structure and a method for making an edge insulation having an edge insulation structure.
• a dwelling is insulated all around, i.e. walls, roof and floor are insulated, and especially insulation in the transition areas between floor and wall has been inadequate for many years.
• a foundation is constructed with a concrete base and one or more finishing layers of blocks made of lightweight aggregated concrete and cement, which has been considered to be an adequate solution for many years.
• the floor is typically made with an insulation and capillary break layer constituted by polystyrene foam, which is perhaps better known under its trade name Flamingo. Other types of insulation material have also been used.
• a 10 - 15 centimetre layer of concrete is applied which then constitutes a floor plate for being covered with suitable and desired flooring. The surface of the cast floor plate is aligned with the upper edge of the foundation and is thus level with said upper edge of the foundation.
• the inner and supporting wall - the back wall and the outer wall/or building envelope are positioned on the foundation.
• Insulation material for instance glass wool or rock wool
• door and possibly window structures may be placed in certain places on the foundation, replacing the inner and outer walls.
• the above-mentioned blocks of lightweight aggregated concrete have been developed to now comprise a layer of insulation material between the outer and the inner sides of the blocks.
• a strip of insulation material for instance polystyrene foam between the foundation and the floor plate, which method has a considerable effect.
• DE 29803649 A describes an edge structure comprising an F-shaped edge rail used for levelling out a concrete layer, wherein on one side the edge rail comprises an adhesive layer adhered to the wall, and wherein on the other side the edge rail comprises two horizontal faces.
• the uppermost face is positioned in the same level as the concrete layer, whereas the lowermost face rests on top of the insulation material, causing the concrete layer to extend over the insulation material.
• This construction has the disadvantage that the effect of the insulation between the foundation and the concrete layer is practically eliminated, as the concrete layer extends all the way to the foundation, resulting in the thermal bridge barrier only being constituted by the thickness of the adhesive layer.
• the edge rail must be attached to the foundation, it is not possible to increase the thickness of the insulation material between the foundation and the concrete layer and hence increase the insulation effect.
• the objective of the invention is to provide a solution, according to which an insulation material of an unprecedented thickness is arranged between the periphery of a floor plate and a foundation, a fixed and supporting underlay being provided in the transition between the floor plate and this insulation material.
• the invention relates to an edge insulation structure.
• the edge insulation structure according to the present invention is novel in that the edge rail comprises a first flange arranged in such a manner that it at least substantially covers the face facing upwards of the elongated edge insulation, a second flange for abutting the surface of the floor plate and a third flange for abutting a side face of the edge insulation, the first and second flanges extending from each their side of the third flange.
• edge insulation may be of an adequate thickness while no "soft" edge appears along one or more edges of a floor plate, resulting in mounting difficulties and other undesired effects.
• the so-called soft edge is constituted by insulation material which, in order to ensure adequate insulation capabilities, extends all the way up to the level of the surface of the floor plate. Especially, in the event that carpets or other flooring are/is to be mounted directly on the floor plate, this edge insulation poses certain challenges.
• edge rail By means of an edge rail according to the present invention, a fixed and not least supporting surface may be established above the edge insulation while a mechanical separation of the edge rail and the inner wall, door and/or window structure is maintained. This separation need not be more than a few millimetres, which is enough to prevent direct heat passage from the edge rail to the inner wall.
• edge rail it is possible to make an edge insulation structure with a thickness of 100 to 200 millimetres, if desired. Obviously, edge insulation structures with smaller as well as larger thicknesses may also be made. In the following, several different embodiments of the edge insulation structure according to the present invention will be presented

• These anchoring elements may be longitudinal flanges or other protrusions on the faces of the edge rail facing the cast floor plate.
• the edge insulation structure according to the present invention may advantageously be made of metal, plastic, a fibre composite or a wood or cardboard material.
• metal or plastic may for instance result in certain advantages, whereas in other circumstances, fibre composite, wood or cardboard may be more desirable.
• the edge rail may advantageously comprise at least one elongated foil path which is flexibly arranged for connection with adjacent building elements and thus constitutes a damp proof layer and/or a radon barrier.
• the integration of such foil paths into the edge rail provides the evident advantage that the building worker will not have to remember or handle so many different elements, and at the same time the construction process is considerably facilitated, since the mounting is also time-saving compared to the mounting of several consecutive elements.
• the structure may advantageously comprise the edge rail being provided with a longitudinal installation channel arranged between the surface of the edge rail and the edge insulation, said installation channel in the edge rail preferably comprising apertures in the surface for providing access to the installation channel itself.
• access to the installation channel may be provided in order that primarily cables but also other types of installations possibly made after the construction of the building in question may be immediately installed and hidden.
• the edge insulation structure comprises a detachable edge rail. Such detachable edge rail may be mounted directly on the edge insulation material and may advantageously be levelled to the height of the finished floor prior to final fixation.
• the edge insulation structure comprises an edge rail which is attached to at least one face of the edge insulation.
• it is an integrated structure wherein both the insulation material as well as the edge rail are connected and mounted at the same time.
• the edge insulation and the edge rail may constitute a section of an edge insulation, said section comprising means for connection with another section, said connection means comprising e.g. a recess connection, a tongue and groove connection, a dovetail connection or the like.
• connection means comprising e.g. a recess connection, a tongue and groove connection, a dovetail connection or the like.
• a particularly preferred embodiment of the invention relates to use of en edge insulation structure as described above, wherein an edge insulation is attached to the interior side of a foundation, an edge rail being arranged on the face facing upwards of the edge insulation, said edge rail extending from an area near the foundation and away from the foundation and being levelled and mounted at the height of the finished floor, wherein the edge rail is used for determining the height of the floor during casting, and the edge rail is used as abutment for guide rails or other devices in connection with the casting of the floor plate.
